A. (n-1)(n-2)(n-3)
B. (n-1)(n-2)(n-3)(n-4)
C. (n)(n-1)(n-2)(n-3)
D. (n-2)
In order to solve this question we must first expand the equation as far as possible or needed. This is one of the possibilities one must use to complete.
By expanding the equation only to 4! we are able to cancel out the (n-4)! on both the numerator and denominator, leaving us with the answer to our question:
After all these steps have been completed you have now learned how to simplify factorial expressions! :)
